 I am having an issue that appeared to have been introduced by upgrading
 from Ubuntu 15.04 to 15.10.  I went back to the kernel used in 15.04 and
 the issue persists.  In 15.04 and 15.10, I used the 0.28_fixes repository,
 the MythTV version was very similar (maybe a week gap).

 In the mythbackend.log with verbose "record" set, I get the following
 after a random amount of time recording.  Sometimes it happens in 2
 minutes, sometimes 8-9 minutes, and other times 50 minutes.  Sometimes it
 records the show in full (60 minutes), although rare.  If two are
 recording at the same time, both streams do NOT stop at the same time.

 There is a keep alive output every so often.  As you can see in the log,
 it stopped recording after just 2 minutes.  58 minutes later it ends the
 recording and figures out that only 2 minutes were recorded.  It then
 deems it a failure.  I have NEVER had this happen with the Ceton InfiniTV
 4 recorder until the upgrade.  Now I can't stop it or even find the root
 cause.  There is nothing in the syslog/dmesg that happens at that moment
 in time.

 One other change I made beside the upgrade was a reconfiguration of disks.
 At first, I tried raid1 btrfs.  Thinking it might be the issue, I tried
 raid1 mdadm/ext4.  No change in results.

 I saw that 15.10 was relentless in using ipv6.  So I disabled that too.
 Still not change in results.  I did notice the network adapter changed
 from ctn0 to enp1s0.
